Personally, I think that it is great that you can use the API using any client!

By logging in to Google Cloud Platform with your own account, You created a client to use the API, and You made it available by passing the created client information as a script argument.

You login to Google Cloud Platform with your google account, create a client to use the API, and make it available if you pass the created client information as a script argument.

In addition, you can now download Gmail (via Gmail API).
If you run it on the server side, I think that you can sync Gmail.
I think that it is easy to incorporate it because it implements it only by Insert From URL without using a plug-in or the like.

Please look at the sample file and question if there are unknown points such as script!

Although story changes…

Currently, I create a template file that can easily incorporate FullCalendar that can be used in FileMaker Web Viewer.

I might like to sell it at the Web store, so it may be cheap, but it may be sold for a fee!

In that case, I think that you can purchase by all means m(__)m

If you have an API etc. that you would like to integrate, I hope that you can request.
